It was I think Charlotte Corday (or her head, rather) what was supposed
to have blushed (with shame) after decollation [is that word right?]
and being slapped by the executioner. (Who would blame her?)

Am I old-fashioned or what? The 1692 attribution of the
*Desiderata* is obviously phoney, but why should that make it bunk? It is
like setting out to prove that *Hamlet* is not worth reading, because it
was not written by Shakespeare himself but another man who happened to be
called Shakespeare.
Just read it! Despite all its sham, it is still a beautiful text.
As for nuns, I am seldom privy to their prayers.
